CARDINGr-ENGINE.

Application filed. July 12, 1918. SeriaiNo. 244,640.

To all whom it may concern:

Be it known that I, LOREN W. PENNEY, of

Newtomin the county of Middlesex and State of Massachusetts, a citizen of the United States, have invented a new and useful Improvement in Carding-Engines, of which the following is a specification.

In an application heretofore filed by me on November 20, 1917, Serial No. 204:,593, I

have described a means for. cleaning both.

the cylinder card and the doifer by the one stripping brush, which is located between the two and may be moved into engagement with either. My present invention relates more particularly to the mounting of the.

Whereas in my formercase I mounted the stripping brush upon rockable arms, in the present case I mount stripping brush.

the stripping brush in a frame which may be moved horizontally to carry the brush into contact with either the card on the cylinder or the card on the doifer and provide means for so moving it.

My invention will be understood by refer-.

ence to the drawings, in which Figure 1 is aside elevation of a mechanism embodying my invention;

Fig. 2 being a vertical section through the mechanism shown in Fig. 1, the stripping brush being in neutral position, and

Fig. 3 showing a similar section with the stripping brush in position to strip, the cylinder card;

Fig. 4 being a longitudinal partial section through the axis of the stripping brush.

. The parts of an ordinary carding engine are only shown and described in so far as theyare necessary to indicate the application of my invention thereto. I V

A is that part of the casing which covers thev cylinder A A being that part of the casing which covers the doffer A On each side ofthe machine is a bracket B mounted on the cylinder casing A, this through two bushings D one at each end, each lying in a guideway forming part of a plate E connected to the side of the nozzle E this nozzle being shown in my previous application. This plate also has bearings F at each end thereof through which passes av shaft F having a handle F at one end thereof by which it may be turned, and on this shaft at each end thereof and bearing against the hook pieces Z) of the brackets B on the one side and the abutments b on the other side is an eccentric F which is mounted on the shaft F It will be seen from this construction that the turning of the handle F and hence the turning of the eccentric F will move the plate E of the nozzle together with the' nozzle backward and forward horizontally, and hence will move the stripping brush C either toward the 1 position, the bushings D of the shaft being thereby slid along the guideways in the bracket. At 6 is an adjustable screw stop which is adapted to engage the bushings and prevent the stripping brush from being moved too far into the clothing of the doifer. e is an adjusting screw to adjust the position of the bracket B after which the bracket is clamped by the nut b.

The nozzle E 'is mounted as described in my previous application and carries on its rear lower surface a foot-piece e which may be set into a suitable indentation a in the top surface of the casing or cover A to steady it.

The nozzle E is connected with a pipe E up through which the strips are drawn by a suction fan or pump. As it is desirable that when the stripping brush is not in use this passage should be closed, I have provided a gate or damper G'of sufficient length and suitably mounted to slide horizontally and so close the opening E between the nozzle E and the pipe E and this gate issamelength as the. stripping brush,- the pipe when the strippingb projects upward from the center of the nozzle only and is of comparatively small diameter as shown.

I provide anopening G midway between the ends of the nozzle, and I prefer to provide a closure G which is hinged at 91: to the lower end of the pipe E and rests upon a part'g mounted on top of the nozzle so that access may be had tothe interior of must be an "opportunity'for air to pass freely I into"theentrance'ofthe nozzle carrying the stripswithit; "Ihfave provided a cover H, which iirFig. 3 is shown open,'and in Figs, 1"and'2 is shown closed as would be desirable when the stripper is'not in use. This cover His "so shape'd'that'when in place it completes the peripheral portion of the casing A to'the cylinder, andit is hinged at h to a bracket H which i's'pivotally connected by the arm H with thefhan dle' This bracket fH is mountedi'on a plate H piv-' otally' connected to a bracket 723 loosely mounted on the shaft F this construction being suclrthatwhen the handle G is mas" lower positio'n shaman-F g. 2 the cover is in position to form part of tl epasing a and so, close-in the cylinder A (see Fig 2) closes the op'eningbetween the' nozzle and th'e' chamb'er containing the 'strippingfbrus'li.

' When; however,'thestrip ing brush is in stripping the cy1i1-1 c1ereara, l the handle G beingurawn -upina; the pesition shown in Fig.3 to open thegate G, also draws the cover H lifting it and opening it atits" the. brush to have working engagement the cylinder card. Moreover, this action also liftstheplatefH sethatthereisample access Mair-refine nozz'le'E handle G? and earring eingu en substantially in line the parts arelocked in placeifOfcourse the lower "the handle: 'Gj is dep ressedlfroiii' its position inFi'g, 3',1the more 'secuireiwill be thelocking of'the p "I prefer to prp'viagatarm guideplate at each'fend ofthe mach ne so that in dropping the cover Hfi'nto place its lower guidedinto its closing position.

It has seemedunnecessary to show the strippingbruslrC in contactwith the doflfer, but it'will' be easily understood that" upon end will engage these-guide land turning the handle F from its position in Fig. 3 through an angle of 90 degrees to the left. the nozzleand the plates E attached, to its end and in which the stripping brush is mounted will by means of the eccentric be drawn to the left, so that the stripping brush will enter the card on the dofier A it being remembered. that the bearing offlthe shaft F carrying the eccentric F is always in fixed position with relation to the nozzle. The hinging of the cover H at h not only allows it to find its place as part of the easing of the'cylinder, but also allows it to be liftedinto such position as not to; interfere with thestripping of the card" by the stripping bru'slii The abovel v believe is the preferable embodiment'of my invention, but Ido not mean to limit myself thereto, its purpose being the mounting offastripping brush as part of acarding engine in suclraway that without rocke riarms, which must project more or less outside theplanesof the casings A p and A51 mount the stripping brushpractically within the machine itself. And while the mounting of the casing H isshown in its preferred form, other means maybe provided for the purpose.

What Iclaim as my invention is 1. "In a machineof the'fkind described, a cylinder, a doff'er, guideways located between said cylinder and said. dofi'erfarotary stripping brush, amounting for said brush at each end thereof, said mountings being mounted in said 'gnideways.
